i To all whom it may concern:

Be it known that I, HARRY A. DOUGLAS,

: a citizen of the United States, and resident tate its "manufacture,the assembling of its.

adapted for pse on automobiles; and-its object is to improvetheconstruption of the frame or body of the lamp in order tofaciliparts, and repairing. These objects are attained in the structurehereinafter-described and illustrated in the accompanying drawings, inwhich l Figure 1 is a side elevation of the lamp,

some portions being shown in section; Fig.

2 is a horizontal section through the body of the lamp, some parts beingomitted; Fig. 3 is a detail in perspective of a part of one of the outerclampin retaining the side panels; Fig. 4: is a detail in perspective ofan inner frame bar cooperating with the outer member; and Fig.

5 is adetail in perspective of one corner of the lamp, its open-ablepanel partly raised.

The lamp comprises'an upper or top sec-- tion, generally. designated bythe numeral ,10, a bottom section generally designated by the numeral11, a series of "posts or bars uniting the top and bottom sections andforming a part of the frame of the lamp,

side panels, shown as four in number, inte-r-' posed between the top andbottom members andseat'ed againstthese members and the frame postsandheld thereto by means of clamping bars, which also serve to reinforcethe frame posts or bars to more rigidly unite the top and bottomsections.

The top section 10 is of sheet metal and comprises a dome 12, carried byan outstanding tlange 13. The bottom 11 is also.

of sheet metal and comprises a cup is. for holding the oilfontla), thiscup being carried by an outstanding flange 16 and having adownwardly-projecting extension 1.7 which mayrest upon and be secured toa supporting bracket (not shown).

The lamp is shown as being square, and its top and bottom sectionsareunited by a series of posts gr bars 22,'1ocated at the cormembers forsecuring the top and bottom of the lamp together and k to the slidingpanel ners These bars maybe stamped out of sheet metal and have theirends turned inwardly'forming flanges 23, 24 which are seated against theinner surfaces, respectively, of the top flange 13 and the bottom flange16. The body portion of eachof these bars extends across one corner ofthe lamp, the center portion being flat audits side portions being bentinwardly to form shoulders 22 perpendicular to the planes of the panelsand then laterally to form out;-

standing flanges 22" parallel to the planes of 1 these panels andforming seats therefor.

As shown, two of the panels 26, 27, are of glass, each being seatedwithin a metal frame L-shaped in cross-section, theouter flange ofthisframe 26 bearing against the outer face of the glass and its instandingflange 26 being perpendicular to the plane I of the panels and fittingand sliding upon the shoulders 22 and upon the outer faces of theflanges 13 and 16, forming a snug fit with the body of the lamp for theexclusion of air currents and dust. The third panel 30 is of metal andhas its edges flanged, as shown at 30 to fit againstthe shoulders 22' ofthebar 22 and upon theouter faces of the flanges 13 and 1.6. This panelmay be provided with a socket lug 31 for engaging a supporting bracket(not shown).- The fourth panel comprises a metal frame 32 and a slidingplate 33 having its edges folded inwardly, as shown at 34, for engagingand running upon out turned flanges of the frame portion. A lug 36 isattached for convenience in raising it, and spring lingers 37 areattached to the upper portion of the frame member 82 for engaging ribs38 formed on the inner face of the pane adjacent its bottom, andaffording means for holding this panel in its raised position to permitaccess to the interior of the lamp. The inner portion 32 of the frame 32has a sliding engagement with the shoulders 22 of the frame bars 22,

The several panels are secured'in place by means of clamping bars 18which have their endsfianged inwardly, as shown at 19, 20 to over-lapthe outer faces of the flanges 13 and-l6,-such flanges being slotted, Yas shown at- 21, for the reception of retaining screws 19? and 20, setthroug suitable apertures in the top and'bot-tom embers,

and engaging threaded apertures, as 25, int?- of the members 30 and 32.

the instanding flanges 24 of thejrame bars 22. The marginal portions 18pf the bars 18 are bentt'o fit upon the outer faces of the panel frames26* and the-marginal portions Screws 28 are set through suitableapertures in the bars 18 screws 28 have been firmly set up.

The font 15 andthe burner carried thereby are of any approved form. Thewickraising spindle 39 of the lamp may project outwardly and be lodgedin a recess 40 formed in the' frame 32, thus permitting the freemovement of the sliding panel 33 and being held thereby againstdislodgement from its recess.

The various parts of the lamp are held securely and rigidly togetherbymeans of the screws set through the clamping bars. Should it becomenecessary to replace a panel, the screws are emoved from one pair ofclamping bars, pe init-ting the ready removal of the damaged panel andthe insertion of a new one.

The invention is shown in connection with a top draft lamp, but maybeused ina lamp employing any type of burner or mode of ventilation.

I claim as my invention:

1. In a lamp, in combination, a top section, a bottom section, a set ofupright bars uniting the top and bottom sections and having their endsint-urned and bearing, against the adjacent faces of such sections,panels seated against such bars, clamping bars cooperating with thefirst-mentioned bars for securing the panels, and having their endsinturncd and engaging the top and bottom sections and means for securingthe two sets of bars to the top and bottom sections.

2. In a lamp, in combination, a top section, a bottom section, a set, ofupright bars uniting the top' and bottom sections and having their endsinturned and bearing against the adjacent faces of such sections, panelsseated against such bars, clamping bars for binding the panels to thetirst-mcntioned bars and having their ends inturncd and engaging theouter t'aces ot' the top and bottom sections, and means for securing thevarious bars to such sections.

3. In a lamp, in combination, a top section, a bottom section, a set offraming bars uniting the top and bottom sections and having their endsinturned and bearing against the adjacent faces of such sections, panelsseated against such bars, clamping bars for binding the panels to theframing bars and havin their ends intnrned and slotted and engaging theouter faces of the top and bottom sections, and screws setting throughthe slots of the clamping bars and in threaded engagement with theframing bars.

4. In a lamp, in combination, a top section, a bottom section, a set offrame bars uniting the top and bottom sections and hav ing their sideportions angular in cross-section forming shoulders perpendicular to theplanes of the side faces of the lamp, and panel-receiving seats parallelwith such side faces, panel-frames angular in cross section forinclosing the panels and engaging the shoulders of t-hcbars, panelsseated Within the frames and clamping bars binding the panel-framesto'the frame bars.

5.'In a lamp, in combination, a top section, a bottom section, a set offrame bars uniting such sections and having their marginal portions bentto form panel seats and panel-engaging shoulders, a set of panels='e11gaging such seats and having instanding 'flanges shdably engagingthe upper shoulders and the margins of the top and bottom sections andclamping bars binding the panel sections to their seats.

6. In a lamp, in combination, a top section, a bottom section, barsarranged in pairs detachably uniting the two sections, a frame clampedbetween the members of two pairs of such bars, and a panel slidablycarried by such frame.

7. In a lamp, in combination, a top section, a bottom-section, barsarranged in pairs detachably uniting the two sections, a frameclampedbetween the members of two )airs of such bars, a panel slidably carriedy such frame, and springs for restricting the movement of the panel. v

S. In a lamp, in combination, a body frame, panels fitting the bodyframe, one thereof being removable, a font seated within the body andhaving a wick-raising spindle projecting beyond the walls of the body,the. opposite members of that part of the body frame receiving theremovable panel having grooved margins forming a slidcway for such paneland one of such frame members having a recess for receiving thewick-raising spindle extending through its said grooved margin.
